I had a partner along to help with calling and packing when I drew a Utah limited draw tag. 4 days into the hunt he developed medical problems and I had to drive him to an airport so that he could fly home. It threw me for a loop at first. I had gone into it thinking I'd have someone to help and the sudden change to going solo had me thinking I should just cut things short too. But I put that out of my mind and decided to make the best of it. Long story short, I killed the bull of a lifetime. Packing out was a struggle, but I don't think much about that anymore.
One thing I would suggest is to carry plenty of rope and some type of a pulley set up so that you can move an animal while working on it. My bill died in an awkward spot and I had a heck of a time getting him broken down.
